- Cell specializations are usually a modification or elaboration of one of the basic cell functions. (True or fa1se?)arrow_forwardDifferentiate among the terms cancer, tumor, and neoplasm. Note. There is a little confusion about the terms "tumor" and "neoplasm". Think about cancers such as leukemia and other blood cell cancers. Are they tumors?arrow_forwardCancer is a complicated series of diseases characterized by over-proliferation of cells within a tissue. While in some instances the primary tumor is the ultimate cause of death, in many cases the primary tumor metastasizes, or moves, through the lymph system to invade other tissues. The migration of tumor cells requires changes in the adhesion properties of the cell that allow it to move and invade more readily. There are several molecules involved in cell-to-cell connections and cellular architecture: laminins, matrix metalloproteinases, cadherins, and integrins. While mutations in genes that control the cell cycle or recognize DNA damage are the causes of tumor cell formation, tumor cell spread to other tissues may be caused by mutations in the genes the code for these extracellular proteins. The loss of cellular connections, cellular identification and signaling, and tissue structure may lead to the release of expanding tumor cells into the circulatory and lymphatic systems.

Tumor-initiating viruses often target RB1 for inactivation. What advantage would a virus gain by inactivating RB function in the host cell? Human papillomavirus (HPV) is an example of a virus that inactivates RB and causes tumors. Which cancer is HPV infection most closely associated with? How is HPV able to inactivate RB?

- Tumors associated with breast cancer usually arise from either epithelial cells or fibroblasts. Because optimal treatment differs depending on the cellular origin of the tumor, it’s important for doctors to determine which cell type is present in a tumor. Unfortunately, the distinctive morphology of epithelial cells is lost when they become cancerous, so this determination cannot be made based on cell shape alone. How might determination of the class(es) of intermediate filaments present in tumor cells aid a doctor in figuring out which cell type is involved in the tumor?arrow_forwardWhich component of cell division machinery is frequently targeted by anti-cancer drugs? Can you explain the common side-effects of chemotherapy (e.g. hair loss, mucositis) based on this information?arrow_forwardDescribe the changes that cells go through to become cancer.arrow_forward
